SIGNAL.

Specification of Letters Patent.

Application led February 20, 1918.4 Serial No. 218,266. 1

I make a turn.

It is the object of the invention to provide a signal of the character above set forth that will be simple in construction, certain in operation and one which will display a very distinctive and well recognized signal indicating danger, that will be visible from the rear of the machine upon which it is located.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

' In the accompanying drawing:

Figure 1 is a longitudinal vertical section of a signal constructed in accordance with the invention and with the parts in the position they occupy when the signal is displa ed.

Fyig. 2 is a like view with the parts in the position they occupy when the signal is not displayed and Fig-3 is a vertical section upon line 3-3 of Fig. 1 looking in the direction indicated by the arrow.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing 5 designates a cylindrical casing one end of which is flared as indicated at 6 and the other end of which carries a bracket 7 by which the cylinder 5 may be secured to the windshield or other convenient part of a motor vehicle with the cylinder 5 projecting at right angles to the line of travel thereof and beyond the side thereof.

The rear end of the cylinder 5 has an opening 8 formed therein for the passage of a stem 9, the inner end of which carries an operating handle 10. A stop collar 11 is disposed upon the stem 9 outwardly of the cylinder and limits the movement of the stem into the cylinder. The stem 9 is pivoted at 12 to a link 13 and this link is pierced at 14 for the passage of a strip of spring metal 15. The oppofslte ends o the strip 15k are bent`v upon'themselves asindicated at 16 and between the`portions 15`and 16 is engaged a band of red fabric 18. The link 13 carries a collar 19 and ay spring 20 bears between this collar and the rear end of the cylinder 5.

Under normal conditions the parts lie in the position illustrated in Fig. 2, at which time the stem 9 lies at right angles to the cylinder 5 and the spring 2O is compressed. At this time the spring 15 and the red fabric band 18 are collapsed and drawn into the cylinder 5 where they are out of sight. When it is desired to display the signal the handle 10 is grasped and the stem 9 is brought into alinement with the link 13, the handle is then released and the spring 20 acts to move the parts to theposition illustrated in Fig. 1. As the spring strip moves out of the mouth of the tube it expands and brings the red fabric band to the fan formation illustrated in Fig. 1 thus forming a signal of fan shape and of a distinctive color that will be visible for a considerable distance to the rear.

It is to be noted that by virtue of the novel arrangement of the parts wherein the strip 15 is bent upon itself at 16, the band 18 is eiiiciently held while at the same time a metal surface is provided which acts upon the Haring mouth of the tube when the signal is to be moved to the position illustrated in Fig. 2, and which strip is collapsed and thereby collapses the fabric portion of the signal Without the fabric portion of the signal coming into contact with the tube or cylinder 5. v

The structure herein shown and described is a simple and inexpensive one that may be lmanufactured at a small cost but will be entirelv efficient for the purpose for which it is intended.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairlv come within the spirit of the appended claim.

Having described my invention what I claim is:

A device of the character described. comprising a vrelatively stationary tubular casing having one end open and its opposite end provided with a head having a contracted opening, a signal device adapted for longitudinal movement within the stationary tubular casing and to automatically Patented Dec. 1o, 191s.
